In California I believe that they're given that a try over a stretch of canals. As long as they are robust to windy weather, and don't interfere with water fowl, then sounds like a win-win. There are so many parking lots, where cars just bake in the sun, that would benefit from solar parking roofing. Cars would have to cool less, and the landowners would have another steady stream of income (its the upfront costs that are the problem as always). TBH I look forward to a time where you can pull into a supermarket, shaded by solar panel roof, and I can hook up my EV to charge while I'm pulling groceries from the shelves. (Not that I expect the solar to be able to provide all the power needed for EV charging).
